There are a few in our club and I posted a pic in the stuck section of Lens Rubi (To The Wall). You do have to drill holes in the window frame and the body but I'm not sure of the size. The install was fairly simple though.
Bah, mine was supposed to be here Friday but I guess it'll be Monday. I'll have it on before the weekend though as I'll need it. According to ARB it does fit but doesn't line up exactly with the A pillar as it does for 97-'02 model TJ's. We shall see.
One of the guys in our club installed his. He said it went it with not to many problems. Biggest problem was the guys at the Auto Hobby Shop that freaked about him taking a hole saw to the side of a 30K vehicle. Understand that a wrench is a dangerous object in his hands. The install looks really good. Hardest thing was drilling out all the holes. Especially the ones inside. His has A/C and didn't have any problems. Now OBA is another story since the new air intake routes right into that area.
I'm actually not impressed with how hard it went on and actually looks like crap up close. You really need to use the soapy water method of laying it down and de-bubbling rather than using their method.
I have a friend that will airbrush a larger version for $200 if I get around to it.
